Application filed October 9, 1907. Serial No. 396,643.

Be it known that we, HENRY F. FIscHER and MAX H. DETTE, citizens of the United States, residing, respectively, at Corona, Queens county, State of New York, and at Woodclifi', Hudson county, State of New Jersey, have invented certain new and useful 1m rovements in Ice-Cutting Machines, of which the following is a specification.

Our inventionrelates to the class of cutting machines designed to saw rectangularsections of ice from a block thereof, our main object being to attain simplicity both in structure and o eration to the end that the machine may e successfully manipulated by unskilled labor.

Incidentally we produce a comparatively cheap, substantial apparatus which, while adapted to the requirements of small consumers has a capacity for cuttin large quantities of ice in a comparative? s ort time,-

since the manipulations mvo ved are simplev and may be sa ely executed with expedition. In the accompanying drawings, igure 1, is a plan of our machine; Fig. 2, is a front elevat'on; Fig. 3, is a plan showing the ice holder advanced over the primary set of saws; Fig. 4, a like view showlng the carriage and ice holder advanced over the secondary set of saws and the severing saw; Fig. 5 is an elevation of the right hand end of the machine; Fig. 6, a section on lane of line 6-6 Fig. 1; Fig. 7, an enlarge sectional detail of a section on line 8'8- Fig. 1; Fi 8, a sectional detail on an enlarged scale ta en on plane of line a;a;-

Fig. 8; Fig. 9, a side elevation of the carriage frame; Fig. 10, an

end elevation of the same; Fig. 11, a plan of the holding frame; Fig. 12, is a section on plane of line 12-12 Fig. 11 F igu13, is a section upon plane of line 13-. 13 Fig. 11; Fig. 14, is a sectional detail on pn enlarged scale on plane of line 14-14- A, re resents the frame work generally, upon w 'ch the table B is supported, being preferably hinged thereto, as at a, a, and

eld in its normal position thereon by screw bolts 0., a, or equivalent means, so that access may be conveniently had when desired to the under or reverse side of the table.

sets of saws 1, 1, and 2,2, 'ranged in vertical planes,

square flat plates, cubes, or ot That is to say, by releasing the fastening devices a,, a, the table B may be swung upon its pivotal points of support a, a, into an approximately upright position. As all the operative parts are mounted upon the table B the advantage of thus supporting the ta ble is obvious.

C is the power shaft mounted upon the under side of the table in suitable bearings, and carrying a series of what may be designated as primary circular saws 1, 1, the peripheries of which protrude through slots b, b, in the table B. A miter gear 0, on the power shaft O engages with a corresponding gear (1, on the end of a shaft D, the underside of the table at right angles to the said power shaft C. Th s secondary shaft carries a secondary series of circular saws 2, 2', the peripheries of which protrude through slots b, in the table B. Beyond this secondary set of saws 2, 2, is adjustably mounted'a single saw 3 in a plane at right angles to the planes of the saws 2 2. This single saw 3 which may be designated as the detaching saw is supported upon an arbor E, mounted in suitable bearin s in a bracket b secured to the under side 0 the table B, said arbor E carrying a pulley e, which is driven by a belt e, passing over the idlers F and F (mounted on brackets If, on the under side of the table B) and over the pulley c, on the power shaft 0. The primary and secondary and the severing saw in a horizont lane although this is not essential provide the relative arrangement of the several saws is maintained.

, Provision ismadefor adjusting the detaching saw 3 in any suitable manner, as by an adjustable step for the arbor E as shown in mounted onare preferably ar-' Fig. 8 in which the arbor is supported upon I a ball 6, Testing upon the follower e, which is regulated in position by means of the screw Obviously the height of c, and lock nut e.

3 above the surface of the the detaching saw table will determine the de th of the rectanlar sections of ice severe from the bottom of the block thereof in the holder H. I Hence, ice sections of various lengths and thicknesses of rectangular paralleleplipedal form, as er rectangular set of saws 2, 2.

parallelograms, may be attained by the adjustment of the detaching saw 3; and the number anddistance apart ofthe saws in either or both of the series 1 and 2, may also be varied to attain difierent results in the size and shape of the ice sections although the latter will necessarily always be rectangular in outline.

A rectangular carriage G rests upon ways b 6 b, on ,the top of the table, said ways being parallel to the planes of the secondary The intermediate way I), is a groove in which rest tongues g, g, on the carriage G (see Figs. 5 and 6) which is also formed with bearing surfaces 9, and 9 for engagement with the ways I), and 6 The carriageG is locked in its retracted position on the right of the table B by means of a spring latch 9 shown in detail in Fig. 7, or by any other well known mechanical expedient. Attached to the left side member of the carriage G is a shield 9 which is of sufficient extension to cover the. secondary saws 2, 2, and the detaching saw 3 when the carriage is retracted, so that all danger of accidental contact with said saws is avoided.

The longitudinal side members of the carriage G are parallel, and constitute ways upon which the ice holder H, travels.

The ice holder H consists essentially of a rectangular frame the side members of which are rectangular in cross section, the-upper and outer flanges h, h, resting upon the longitudinal side members of the carriage G and their inner flanges h, h, engaging with facings g g", on said longitudinal members of the carriage; or any other arran ement of parts may be resorted to that will admit of the reciprocation of the ice holding frame H upon the carriage. The ice holding'frame when in its retracted position is locked to the carriage G, by means of a spring latch if, like unto that shownin Fig. 7. it is a shield attached to the front of the frame H, to guard against contact with the primary saws 1, 1,

when the frame is passed over them; and h, is a handle by which both the ice frame II and the carriage G are moved as hereinbefore set forth. The depth of the ice holding frame is such that its lower edges are above the plane of action of the saws; and the longitudmal side members of the carriage are also open and above said plane except where the bearings g and g occur.

The block of ice is held in the frame H by any suitable clamping device K. In the form shown in the drawings, is is a jaw pivoted to the frame and having a bearing limb 76, which is ribbed horizontally, and an outer bifurcated arm lei-which straddles the shouldered head Z, of a sleeve Z, slidable u on a bar Z Between the shouldered headl which are ribbed horizontally and cular saws, a fixed part of the holder H, a spring I, is l the other,

interposed which tends constantly to thrust the bearing limb 7c, of the jaw inward against the block of ice when placed in position in the frame H. The jaw k, is retracted against the resistance of the spring Z by means of a lever Z pivotally connected with the head Z, of the link Z. The inner sides of the holder H are formed with contacts M, for the ice,

to insure a substantial hold or purchase on the ice and to sup ort it against all tendency to slip vertica ly.

In practice the arts being in the position shown in Fig. 1, t e bearing 7c, is retracted by means of the lever Z and a block of ice placed on the table within the holder H, with two of its sides resting against the ribbed contacts h as indicated. The lever Zi, be-

mg now released, the spring I, forces the bearing 7c, against the opposed side of the block of ice, thereby locking it firmly in position within the holder H, and practically suspending it thereon, so that it is supported independently of the underlyingsurface of the table. The spring latch h is then raised and the ice holder advanced over the primary set of saws 1, 1, as shown in Fig. 3, and then retracted to its former position where it is again locked to the carriage G, by the spring latch h The spring latch 9 is now raised and the carriage G and holder H 'moved from right to left over the secondary set of saws 2, 2, and the detaching saw 3 as shown in Fig. 4, the sections of ice falling from the latter into a suitable receiver or conduit i. The carriage is'now retracted to its former position and again locked to the table by the spring latch g The block of ice being now released by means of the lever Z falls by gravity to the surface of the table when it is again clamped by the release of the lever, and the operations above described repeated.
